What's happening
Anastrozole is currently affected by 6 active shortage reports filed with Health Canada by MINT PHARMACEUTICALS INC, TARO PHARMACEUTICALS INC, PHARMASCIENCE INC, BIOMED PHARMA and 2 others.
The reported causes are: disruption of the manufacture of the drug; other (please describe in comments); requirements related to complying with good manufacturing practices. Manufacturers must report shortages, but end-date estimates are their own projections and often move.
If your usual product is affected, a pharmacist is the fastest route to a solution: they can dispense an unaffected manufacturer's equivalent when one exists, and in most provinces can adapt doses or substitute a therapeutic alternative without a new appointment.
Anastrozole is classified under “HORMONE ANTAGONISTS AND RELATED AGENTS” (ATC L02BG).
